WILI-IELM Dfi'SKOXV, OF BERLIN, GERMANY CLOSURE DEVICE FOR PERFUME BOTTLES OR THE LIKE Application filed December 4, 1928, Serial No. 323,686, and in Great Britain December 23, 1927.

' This invention relates to improvements in the construction of perfume-bottles, the

necks of which are provided with a metalhc closure-cap having a sprayingor gutteraperture.-

The object of this invention is, to simplify and cheapen the manufacture of the bottle and of the closure-device, as well as the attachment of the latter and to limit the rotary 10 movement of the closure-cap having a spraying opening placed eccentrically in the top of said cap.

The invention consists of the novel arrangement and construction of the neck of 15 the bottle, which is provided with a flange and with a spraying-aperture eccentrically arranged in the flange, as well as with a stop or projection beneath the flange covered'over by a resilient washer having a spraying 20 opening eccentrically arranged to register with a spraying aperture of said cap, which is provided with several convex embossments projecting under the edge of the flange to hold the washer in a slide-contact with said flange and to limit the rotation of said cap and washer.

The embossments of the cap are stamped into its cylindrical wall extending downward beyond the lower edge of the flange of the bottle-neck and are pressed inwards in order to secure the tight fitting of the washer and cap on the surface of the bottle-neck.

In the drawing, like characters refer to corresponding parts throughout the several 35 figures.

Referring to the drawings: Figure 1 is a sectional View of a portion of a perfume-bottle provided with a closure device embodying this invention showing the 5 closure device in closed position on the line TI of Fig. l.

Fi 2 is a similar sectional view showing the closure device in open position on the line ITII of Fig. 5.

Fig. 3 is a top view showing the closure device in closed position.

Fig. 4; is a cross-section on the line IIIIII of Fig. 1.

Fig. 5 is a similar cross-section on the line IVIV of Fig. 2.

Fig. 6 is a sectional view of a modified form of the bottle on the line V-V of Fig. 7.

Fig. 7 is a top-view of a modified form of the bottle-neck.

Fig.8 is an elevation of the closure device in its operative position, and

Fig. 9 is a cross-section on the line VIVI of Fig. 8.

As shown in Figs. 1 and 2, the neck 1 of the bottle is provided with a circular flange 2, which is moulded integral with the bottle and has in its upper surface the discharge outlet thereof. This outlet is formed as a restricted spraying opening 3 arrangedeccentrically of the flange 2. The neck 1 of the bottle is provided below the flange 2 with an inte ral stop or projection 4, preferably a longitudinal rib, on the neck of the bottle.

A cylindrically shaped metal cap 5 is pushed over the flange 2 forming a pivot which enables the cap to be turned smoothly roundsaid flange. A closure disc or washer 6' of any suitable material such as cork, rubher or the like, is fixed inside the'metal cap 5 and bears directly on the broadened and flattened top of said flange 2.

The washer 6' and the top of the cap 5 are provided with spraying apertures- 3, which are both situated at the same distance from the centre of the flange 2 and correspond with each other as shown in Fig. 2.

The cylindrical portion of the cap 5 reaches down below the flange 2. The cap 5 is provided at itscylindrical portion with notches T and extensions bent inwards or convex embo-ssments 8, 8 for the purpose of pressing the cap on the neck of the bottle and ensuring an intimate slide-contact of the washer with the top of the neck around the spraying aperture. The extensions 8, 8 get pressed in beneath the flange, when the cap; 5 has been pushed .over the neck of the bottle and at the same time the washer 6 has been compressed by a force depressing the top of the cap 5. When this forceis released, the extensions or emb'ossments 8, 8 hold the washer 6 down by reason of their firmness, so that their action causes the washer 6 to be further depressed against the upper surface of the flange for ensuring the sliding rotation of the washer upon said surface and above the aperture 3.

If the cap 5 is turned into the position shown in Fig. 1, the washer 6 shuts'the aperture 3. This turning movement is limited by the extension 8, which abuts against one Side of the stop 4. If the cap 5 is turned back to the position shown in Fig. 2, the washer 6 opens the aperture 3, this backward movement being limited by an extension 8 which abuts against the other side of the step i. The space between one pair of extensions 8, 8 forms a groove, into which the stop 4 fits. The embossments 8. 8 have the double duty of holding the washer 6 in close contact with the surface of the flange and at the same time limiting exactly the rotary movement of the cap both in its closed and open position.

As shown in Fig. 6, the flange is provided with a boss or wartlike elevation rising above the surface of the flange 2. This boss 9 is eccentrically arranged to the flange 2 and perforated through the opening 3. This arrangement has the eflect of ensuring an increased specific pressure between the washer 6 and the circumferential wall of the ap erture 3. When the neck of the bottle is moulded, it sometimes happens that the central portion of the flange tends to drop or godown. This inconvenience maybe counteracted by the arrangement of said boss 9, which surrounds the aperture 3 (see Fig. 7).

The upper cylindrical portion of the cap 3 embracing the closure disc or washer 6 is preferably beaded by a pluralitypf pearlshaped dents 10 fitting into the rim of the Washer in order to secure it tightly in the cap (see Figs. 8 and 9). V

Having thus described my lnvention, I claim:

1. In a closure-device for perfume-bottles or the like, a bottle having a neck provided with a cylindrical flange formed around it, and having formed therein an eccentrlcally arranged spraying opening, a metal cap having an eccentrically placed spraying aperture in its top, a washer embraced by said cap and bearing on the flange, said washer having an opening registering with said aperture, said metal cap having a plurality of embossments bent inwards beneath the lower face of the flange and bearing against the same to secure a close contact between the flange and the washer, a pair of said embossnients being spaced to form a groove in said cap, and a stop on the said neck beneath the flange and projecting into said groove between said pair of embossments to cooperate with said embossments to limit the rotary movements of the metal cap.

. 2. In a closure-device for perfume-bottles or the like, a bottle having a neck provided with a cylindrical flange formed therearound, having an eccentrically arranged elevated portion and a spraying aperture projecting therethrough, a metal cap having an eccentrically placed spraying aperture at the top, a washer embraced by said cap and bearing on said elevated portion of the flange to hold the cap top from depression, said washer having an opening corresponding with said aperture, said metal cap having embossments bent inwards beneath the lower face of the flange and bearing thereon to secure a close Contact between the flange and the Washer, 21 palr of said embossments being spaced to form a groove in said cap, and a stop on the said neck beneath the flange and projecting into said groove to cooperate with said embossments to limit the rotary movements of the metal cap. 7

In testimony whereof I have affixed my signature.
